N2 - FerroElectric Fast Reactive Tuners (FE-FRTs) are a novel type of tuner that may be able to achieve near perfect compensation of microphonics in the near future. This would eliminate the need to design over-coupled fundamental power couplers and thus significantly reduce RF power, particularly for low beam current applications. The recently tested proof of principle FE-FRT is discussed and the theory and practice of FE-FRT operation are developed. These theoretical methods are then used to explore the potential benefits of using an FE-FRT with specific ERL proposals, which are seen as one of the major use cases. Specifically the ERLs considered are: eRHIC ERL, PERLE, LHeC ERL and the Cornell Light Source. Particular attention is given to the substantial peak and average RF power reductions which could be achieved; in many cases these are shown to be approximately an order of magnitude.
